Saliency-Aware Diffusion Reconstruction for Effective Invisible Watermark Removal
This addresses the need for effective watermark removal for web content, though it appears incremental as it builds on diffusion-based methods with saliency guidance.
The paper tackles the problem of removing invisible watermarks from digital images by introducing the SADRE framework, which achieves robust watermark elimination while preserving image quality, as demonstrated through empirical evaluations on state-of-the-art watermarking techniques.
As digital content becomes increasingly ubiquitous, the need for robust watermark removal techniques has grown due to the inadequacy of existing embedding techniques, which lack robustness. This paper introduces a novel Saliency-Aware Diffusion Reconstruction (SADRE) framework for watermark elimination on the web, combining adaptive noise injection, region-specific perturbations, and advanced diffusion-based reconstruction. SADRE disrupts embedded watermarks by injecting targeted noise into latent representations guided by saliency masks although preserving essential image features. A reverse diffusion process ensures high-fidelity image restoration, leveraging adaptive noise levels determined by watermark strength. Our framework is theoretically grounded with stability guarantees and achieves robust watermark removal across diverse scenarios. Empirical evaluations on state-of-the-art (SOTA) watermarking techniques demonstrate SADRE's superiority in balancing watermark disruption and image quality. SADRE sets a new benchmark for watermark elimination, offering a flexible and reliable solution for real-world web content.
